              Behaviour

              Common Kukri is a nocturnal and semi-fossorial species which sometimes shows activity at day time also. Foraging is done terrestrially. Behavior shy, elusive and mostly non-offensive. On provocation throw its body into loose coil by folding tail and making loops of forebody at some height from ground. Inflated neck can be seen at the same time as aggressive response which is followed by mock attacks. On catching such aggressive individuals this species slits the skin of enemy from either side of head with sharp "Kukri knife" shaped tooth.

                          Threats includes killing due to misidentification, road kills, digging its habitat as it’s a semi-fossorial species etc. However this species is well settled in manipulated lands also so habitat destruction seems not affeting its overall population.
